The Gulfstream G350 and G450 received Transport Canada approval to operate at their maximum cruise altitude of 45,000 feet. Transport Canada normally restricts flight to below 41,000 feet unless special conditions are met to ensure against rapid cabin depressurization. To achieve this Gulfstream added its automatic emergency descent mode (AEDM) feature to the two jets. The GV, G500 and G550 were previously approved to operate at 51,000 feet because they are equipped with both AEDM and a secondary pressure bulkhead.
